JOSEPH A. HENSLER, OF AKRON, COLORADO, ASSIGNOR TO THE COMMON SENSE PATENTING COMPANY, OF SAME PLACE.

MONKEY-WRENCH.

SPECIFICATION forming part of Letters Patent No. 608,520, dated August 2, 1898.

Application filed January 2'7, 1898. Serial No. 668,218.

To all whom it mag concern.-

Be it known that I, JOSEPH A. HENSLER, a citizen of the United-States, residing at Akron, in the county of Washington and State of Colorado, haveinvented certain new and useful Improvements in Monkeyrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

The invention relates to the construction of a wrench provided with an adjustable braced jaw and a fixed jaw the shank of which has a socket at one end and a grooved and recessed handle at its opposite end, cooperating teeth on the adjacentfaces of the movable jaw and shank, and a transverselygrooved and locking cam-lever on the opposite side of the shank from the movable jaw, all for the purpose and substantially as hereinafter described.

Referring to the drawings, Figure 1 is a perspective view of they device complete. Fig. 2 is a similar view showing the saw removed from its operative position and showing the locking-lever of the wrench thrown into position for use as a rule or screw-driver. Fig. 3 is a central longitudinal section through the wrench on the line 00 00, Fig. 1; and Fig. 4 is a detail view of the movable jaw of the wrench.

Referring to the numerals on the drawings, 1 indicates the shank of my wrench, provided at one end with a fixed jaw2 and at its oppo- .site end with a somewhat-enlarged handle 3,

suitably adapted to conform to the hand and provided along one side or edge with a longitudinal recess 3 of corresponding width with the shank and having its bottom flush with the edge of said shank.

5 indicates the movable jaw of the wrench, consisting of the jaw proper, slotted "or recessed, as indicated at 6, and a longitudinally-extending locking-block 7, from the lower end of which extends around the shank a suitable guide-band 8, the front extremity of said band being connected to the lower extremities of two diagonal brace-bands 9, ex-

, tending from the lower end of the lockingblock'to the rear extremity of the adjustable wrench proper, upon opposite sides thereof.

(No model.)

The locking-block is provided upon its inner face with a longitudinal recess 10 for the reception of the contiguous edge of the shank, which isprovided with alongitudinal series of teeth 11, designed to be engaged by one or more teeth 12, located, respectively, adjacent to the upper surface of the movable jaw and the lower extremity of the locking-block.

13 indicates a locking-lever provided at its upper end wi'tha cam-face 14, pivotedat said end between the rearwardly-projecting cars 15, formed by the recess in the adjustable jaw. The cam-face 14 is designed to contact with the edge of the shank opposite the series of teeth referred to, and when the locking-lever is moved into its normal position in contact with the edge of the wrench and within the longitudinal recess in the handle the force exerted by the cam-face 14 will serve to draw the teeth carried by the movable jaw into engagement with the teeth upon the contiguous edge of the shank and will thereby serve to securely lock the said jaw in its adjusted position. If desired, the edge of the shank adjacentto the locking-lever may be provided with a series of depressions 16 for the reception of a tooth or teeth 17, carried by the locking-lever, to assist in the secure locking of the parts. The face of the lever 13 is provided with a recess 18 for the accommodation of the guide-band to enable the lever to lie fiat against the edge of the wrench and to be properly positioned in the recess in the handl In order to utilize the extremity of the lever as a screw-driver 19, it is reduced and sharpened, and its inner face is preferably provided with a series of graduations 20, which extend along the entire length of the lever and constitute it a rule, which willgreatly facilitate the use of the device in a large variety of con-' .to increase its usefulness I provide in the outer or end face of the movable jaw 2 the countersunk screw-threaded socket 21 for the reception of the screw-threaded shank 22 of a saw 23, which extends in line with the shank and handle of the wrench. When desired, the saw may be removed by unscrew-' ing its shank from the socket, and for convenience I have formed a saw-casing 24: in the handle for the reception of the saw when not in use, the open end of the casing being closed bya pivoted spring-plate 25, provided with a knob or projection by means of which it may be swung back to permit the removal of the same.

From the foregoing it will be observed that I have invented a simple and durable combination-tool embodying a wrench of novel construction, the jaw of which maybe readily adjusted and securely locked in place, a screw-driver and rule produced by an adaptation of the loeking-lever of the wrench, and a saw, which may be readily attached when designed for use or which may be retained within a casing formed in the handle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In awrench of the character described, the combination with a shank provided at one end with a ii xed jaw and a countersunk screwthreadcd socket, at the other end with a handle grooved on one side and having a covered casing on the other side, of a movable jaw, cooperating teeth on the contiguous faces of the movable jaw and shank, obliquely-arranged braces connecting the movable jaw with its shank, a guiding-loop on the end of said shank extending around the shank of the fixed jaw, a locking cam-lever pivotally connected with the movable jaw on the opposite side of the fixed-jaw shank from said movable jaw provided with a tapering end and arranged to lie normally in the groove in the handle, and a tooth and depressions on the contiguous faces of the locking-lever and shank of the fixed jaw, said lever being grooved transversely to stride the guidingloop on the shank of the movable jaw, all substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
